Absolute poker is a tough site, because it is full of really tight players. The players are better than stars/party and about in the same league as Crypto/Prima players. The rake is the same as
Ultimatebet and the Cryptos, so it sucks at .5/1 and 2/4-3/6. The bonus is very tough to clear at .5/1, but the points accumulate fairly quickly at 1/2, you'll see about 40 hands/100 that reach 10$.
If you play at Absolute rakeback is what you need, since the bonuses which at the moment are bottomless stack with the RB. There are some really good RB deals out there now, I know PSO has 32% RB which is better than the deal I have through Rake the Rake.
With RB and bonii, you are more than playing rakefree at 1/2 full, and from the 2/4 LO8 I play there you'll usually get close to 100% RB.
Points are the best value from PSO, unless you want the nevada jacks, they're worth about 150$, the upgrade points are worth 90$ and the regular points 60$.
